These days I’ve completed the NY schools project and I’ve managed to make a summary of my data analysis projects in GitHub pages and it looks very nice. It is something I will constantly update with more and better projects. I also worked on my CV more and decided to take an online seminar in the University of Economics and Business, where I graduated. I think it will help my CV look better. It has to do with SQL and BI, so it will hopefully be very useful. The price is a bit high but it is an investement so I don’t need to worry about that!
Some interesting observations from the lessons I did on Dataquest today:
Sample standard deviation usually underestimates the population standard deviation. The small correction we add to the sample standard deviation (dividing by n-1 instead of n) is called Bessel’s correction. Here is a paper for variability in categorical Variables.
